OK, by trial and elimination I found that it is a conflict with gigi's buff rules factory plugin and Party buff plugin. I did a clean install and just put the plain version of the pluginenablerordisablerplugin.cs into the user folder. It worked fine. Then I started adding a folder at a time of my plugins until it messed up. So not I found the culprit and have to decide what I want more. Thank you all for the help.

maybe let him know in the corresponding plugin thread because this is a strange behaviour.
